CROSS-REFERENCE TO RELATED APPLICATION(S) AND CLAIM OF PRIORITY

The present application is related to and claims priority under 35 U.S.C. § 119(a) to Korean Application Serial Nos. 10-2014-0072089 and 10-2014-0128539, which were filed in the Korean Intellectual Property Office on Jun. 13, 2014 and Sep. 25, 2014, respectively, the entire content of which are hereby incorporated by reference.

TECHNICAL FIELD

The present disclosure relates to a method and device for selecting a communication service to connect communication by user equipment in a communication system.

BACKGROUND

The Internet, which is a human centered connectivity network where humans generate and consume information, is now evolving to the Internet of Things (IoT) where distributed entities, such as things, exchange and process information without human intervention. The Internet of Everything (IoE), which is a combination of the IoT technology and the Big Data processing technology through connection with a cloud server, has emerged. As technology elements, such as “sensing technology”, “wired/wireless communication and network infrastructure”, “service interface technology”, and “Security technology” have been demanded for IoT implementation, a sensor network, a Machine-to-Machine (M2M) communication, Machine Type Communication (MTC), and so forth have been recently researched.

Such an IoT environment may provide intelligent Internet technology services that create a new value to human life by collecting and analyzing data generated among connected things. IoT may be applied to a variety of fields including smart home, smart building, smart city, smart car or connected cars, smart grid, health care, smart appliances and advanced medical services through convergence and combination between existing Information Technology (IT) and various industrial applications.

User equipment widely used in mobile communication markets generally has a flight mode implemented therein in order to readily interrupt all communication functions in a space where communication is not allowed, for example, in a space of an airplane while taking off or landing. The flight mode can be set by a user on the screen of a smart phone or through a specific physical button, etc. In the flight mode, the user equipment disables transmission and reception functions of all remote and short-range communication. Examples of the remote communication include commercial mobile communication systems, such as Global System for Mobile communication (GSM), Wideband Code Division Multiple Access (WCDMA), Long Term Evolution (LTE)/Long Term Evolution-Advanced (LTE-A), and the like, and examples of the short-range communication include commercial mobile communication systems, such as Wireless Fidelity (WiFi), BLUETOOTH, and the like. FIG. 1 illustrates an example of a method for setting a flight mode of a smart phone. User equipment 100 has a touch screen 105 on the front surface thereof, and a user inputs desired information by touching the touch screen. The touch screen displays a control screen for starting or stopping several functions, and the control screen includes a flight mode icon 110. The user sets or disables a flight mode by touching the flight mode icon. In addition, the user also displays a screen for setting or disabling the flight mode by clicking a specific physical button implemented in the user equipment. Through various methods in addition to the above-described methods, the existing user equipment interrupts all communication.

In the existing flight mode, the user equipment interrupts all the communication. However, the user may also want to interrupt only some communication rather than all the communication according to situations. For example, there is a case where an incoming call is unacceptable in everyday life. The user is not willing to receive an incoming call in a place that requires silence or when an undesired person makes a call to him or her. In the situation where the user cannot receive the incoming call, a ring tone or vibration for the incoming call is unnecessary. Accordingly, in the situation described above, a communication mode appropriate for the user's situation is required.

A Universal Integrated Circuit Card (UICC) is a smart card inserted into a mobile communication terminal. The UICC stores private information of a mobile communication subscriber, authenticates the subscriber, and creates a traffic security key when the subscriber accesses a mobile communication network, thereby making it possible to stably use the mobile communication.

The UICC is manufactured as a dedicated card for a specific mobile communication service provider according to the corresponding service provider's request and released with previously loaded authentication information, for example a Universal Subscriber Identity module (USIM) application, International Mobile Subscriber Identity (IMSI), a K value, and the like, for the network access of the corresponding service provider. Accordingly, the corresponding mobile communication service provider receives delivery of the manufactured UICC to provide it to the subscriber, and thereafter performs the management, such as installation, modification, deletion, and the like, of an application in the UICC using technologies such as Over The Air (OTA), etc. when necessary. The subscriber inserts the UICC into the mobile communication terminal of his or her own to use the network and application services of the corresponding mobile communication service provider, and when replacing the terminal, the subscriber moves the UICC from the existing terminal to a new terminal to use the authentication information, the mobile communication phone numbers, the personal telephone number list, and the like, which are stored in the UICC, in the new terminal as they are.

The standardization group, called European Telecommunications Standards Institute (ETSI), defines the physical shape and the logical function of the UICC to maintain the international compatibility thereof. In terms of a form factor that defines a physical phenomenon, from the most widely used mini-SIM to a micro-SIM and a recently used nano-SIM, the size thereof becomes smaller. Although it contributes much to the compactness of a mobile communication terminal, it is expected that a UICC smaller in size than a recently established nano-SIM is difficult to standardize because a user is likely to lose it. Since the terminal requires a space for mounting a detachable slot due to a characteristic of the detachable UICC, further compactness is expected to be difficult.

In order to solve such a problem, a demand for replacing the UICC by embedding a security module performing a similar function to the UICC in a mobile communication terminal when manufacturing the terminal is emerging. Accordingly, an embedded Universal Integrated Circuit Card (eUICC) structure, which is a UICC that cannot be detached, is proposed.

DETAILED DESCRIPTION

FIGS. 1 through 40, discussed below, and the various embodiments used to describe the principles of the present disclosure in this patent document are by way of illustration only and should not be construed in any way to limit the scope of the disclosure. Those skilled in the art will understand that the principles of the present disclosure may be implemented in any suitably arranged wireless communication device. Hereinafter, exemplary embodiments of the present disclosure will be described in detail with reference to the accompanying drawings. Further, in the following description of the present disclosure, a detailed description of known functions and configurations incorporated herein will be omitted when it makes the subject matter of the present disclosure rather unclear.

The present disclosure gives a description of technology for telephone call and message control. User Equipment (UE) includes a mobile communication terminal such as a cellular phone, a smart phone, and the like.

Hereinafter, the present disclosure relates to a device and method for subscribing to a network in a wireless communication system.

A messenger mode in the present disclosure is a mode for permitting only communication relating to a specific communication service. For various reasons, a user wants to interrupt only some communication. One of them is an incoming call. In an environment requiring silence, the user wants to interrupt only the incoming call causing noise and vibration. Or when the user does not want a spam call, the sender of which cannot be identified, noise or vibration is unnecessary for the user. In cases where the battery residual quantity of user equipment is small, a voice call communication service causes the battery to be rapidly discharged. Accordingly, it is necessary to permit only a text message or an application messenger communication service that restrictively uses the battery. Lastly, for a user's special purpose, for example, for communication between doctors in a hospital, a pager is still used, and user equipment also needs to provide a similar function. Accordingly, in consideration of the aforementioned user requirements, various embodiments of the present disclosure propose a technology for selectively interrupting only some functions. For example, user equipment, according to various embodiments of the present disclosure, interrupts a general incoming call communication service and permits only a text communication service, such as an SMS or MMS, and a messenger application messenger communication in a messenger mode.

An existing text message like an SMS or MMS is permitted in a messenger mode. Although an incoming voice call is interrupted according to various embodiments of the present disclosure, an incoming voice call for a telephone number designated by a user is discriminatorily permitted. When the user designates a telephone number in advance, a call for the designated telephone number is permitted rather than being interrupted. Currently used user equipment utilizes a messenger communication service provided in an application form, in addition to an existing SMS or MMS text message. Many messenger communication services are introduced to markets, and a subscriber exchanges text messages with desired counterparts using an IP Internet network. CHATON SQUARE, SKYPE, KAKAOTALK, GTALK, and the like are examples of such messenger communication services. Communication is also permitted for all messenger applications or only for limited applications designated in advance by a user. The reason for permitting the communication only for the limited applications is to prevent a smart phone from consistently performing communication due to an unintended application.

Since an incoming voice call is usually interrupted in a messenger mode, according to various embodiments of the present disclosure, it is possible to more flexibly set a communication system for supporting the messenger mode. For example, an LTE system identifies whether paging is received, at every Discontinuous Reception (DRX) period. As the DRX period is set to be longer, it is advantageous for saving the power consumption of user equipment. However, a voice call connection is delayed due to the DRX period set to be longer. When an incoming voice call is excluded, the power consumption of the user equipment can be significantly saved by setting the DRX period to be very long. In the case of a text message or a messenger communication service, a degree of delay is less sensitive, compared to in the case of a voice call. When a user sets a messenger mode, user equipment reports the messenger mode to a network and receives setting information according to that the messenger mode.

FIG. 2 illustrates an example of displaying a messenger mode in a UE according to various embodiments of the present disclosure.

A user sets or disables a messenger mode by simply clicking a control icon of the messenger mode in a UE. The user also displays the control icon 205 using a physical button. A UE manufacturer or the user displays the control icon 205 on a screen 200 by performing a series of touch screen or motion operations in advance. The control icon of the messenger mode is also displayed on the screen by pressing the physical button 230 of the UE for a predetermined period of time. The physical button is a multi-purpose button, such as the power button of the UE or a separate physical button. A control icon 225 of the messenger mode is displayed by pressing the physical button and control icons for other purposes, namely, an end icon (210), a restart icon (215), and a flight mode icon (220) are displayed at the same time. The end icon (210) is used to shut off the power of the UE, the restart icon (215) is used to restart the UE, and the flight mode icon (220) is used to interrupt the communication of the UE. In addition, through a separate physical button, the UE is switched to the messenger mode with one-click.

FIG. 3 illustrates an example of a display method in the setting of a messenger mode for a UE according to various embodiments of the present disclosure.

When a user switches the UE from a general communication mode to the messenger mode, it is displayed on the screen of the UE. This is to help the user consistently recognize the mode of the UE, thereby enabling the user to switch the messenger mode to the general communication mode again when it is necessary to receive an incoming voice call. The UE displays the status and a notification bar on the screen thereof. In various embodiments, the notification bar is located on the upper side of the screen 300, and an indication (305) for notifying of the activation of the messenger mode is displayed on the notification bar. The indication is applied to both a general screen and a locked screen of the UE. At a predetermined location on the locked screen 310 of the UE, the activation of the messenger mode is also displayed to be large. When the user does not touch the screen of the UE for a predetermined period of time, the UE switches to the locked screen. The locked screen is for preventing the UE from performing an unintended operation through the user's unnecessary screen touch, and is displayed as a lock icon 315. The UE switches the locked screen to a general screen through a click or motion on the icon. The user identifies a messenger mode indication 320 on the locked screen without having to switch to the general screen to recognize that an incoming voice call is being interrupted. Furthermore, when the user touches the messenger mode indication, a control icon for switching to the messenger mode is immediately displayed, thereby simplifying a mode switching procedure. In addition, a messenger-mode dedicated screen is also introduced. On the messenger mode screen, permitted messenger applications are also highlighted as indicated by reference numeral 330, in addition to the display of the messenger mode activation state 325.

Embodiments of the present disclosure propose network control signaling for supporting the above-described messenger mode. When an incoming voice call, an SMS/MMS text message, and an application messenger are provided to a specific user in the messenger mode, signaling and operations performed by related network entities are different from each other. The present disclosure employs a new signaling message for supporting the messenger mode and a new network server for supporting the messenger mode. In the present disclosure, the new network server is referred to as a ‘messenger mode server.’ In addition, the messenger mode server decodes collected data and distinguishes between data of a messenger application to transfer only message data of a permitted application messenger to a specific UE.

FIG. 4 illustrates an example of a control procedure for an incoming call according to various embodiments of the present disclosure. In FIG. 4, it is exemplified that a user of UE 2 415 attempts to make a voice call to a user of UE 1 400 according to various embodiments of the present disclosure.

Referring to FIG. 4, in operation 420, UE 1 400 switches to a messenger mode according to the user's specific intention or setting. The setting includes at least one of a setting for receiving Access Class Barring (ACB) information from a base station and automatically switching to a messenger mode when an access priority is low to reduce the consumption of a battery, and a setting for automatically switching to a messenger mode in the case of a specific place and time.

In operation 425, UE 1 400 transmits a messenger mode activation request message to a call session control server. The call session control server includes a Call Session Control Function (CSCF) 405 or a Mobility Management Entity (MME). The call session control server functions to handle a part relating to call and session processing and serves as a gateway for an incoming call. The request message is for informing the call session control server 405 that the UE switches to the messenger mode. In addition, the message includes a list of messenger applications that the user is using, and a list of uninterrupted telephone numbers. The message includes a list of messenger applications that are not used by the user, and a list of telephone numbers to interrupt. The request message is used for selectively providing a communication service to the UE.

In operation 430, the call session control server 405 stores the telephone number list included in the message. In operation 435, the call session control server 405 transmits a messenger mode application message to a messenger mode server. The message includes the messenger application list. At the same time, in operation 440, the call session control server 405 selectively provides new setting information to UE 1 400. The new setting information includes setting information to which a very long DRX period is applied to maximize power consumption.

When UE 2 415 attempts to make a voice call to UE 1 400 in operation 445, information on the voice call attempt is reported to the call session control server 405, and in operation 450, the call session control server 405 determines whether to transmit a paging message for establishing the voice call to UE 1. To this end, the call session control server compares a pre-stored telephone number list with the originating telephone number. If the originating telephone number exists in the list, the user of UE 1 400 has to be notified of the telephone number despite the messenger mode of UE 1. In operation 455, the call session control server 405 transmits a paging message to UE 1 400. If not, the voice call has to be interrupted.

In operation 460, the call session control server 405 requests the messenger mode server 410 to process the interrupted call. The messenger mode server 410 functions to inform the user of UE 2 415 that the call has been interrupted due to the activation of the messenger mode in UE 1. The messenger mode server 410 additionally provides a method of communicating with the user of UE 1 400. To this end, in operation 465, the messenger mode server 410 transmits, to UE 2 415, an acknowledgement message including the messenger mode activation information of the counterpart and the messenger application list.

In operation 470, UE 2 415 automatically displays the activation or deactivation of the messenger mode of the counterpart and the messenger application list to the user. The user of UE 2 (415) creates a message using an SMS/MMS text message or the messenger application.

In operation 475, UE 2 415 transmits the message to UE 1 400. If the created message is an SMS/MMS text message, the message is transmitted to the call session control server 405 and then provided to UE 1 400.

In cases where the user of UE 1 400 disables the messenger mode in operation 480, UE 1 400 transmits a messenger mode deactivation message to the call session control server 405 in operation 485.

In operation 490, the call session control server 405 deletes the telephone number list. In operation 495, the call session control server 405 transmits the messenger mode deactivation message to the messenger mode server to inform that UE 1 400 has disabled the messenger mode.

FIG. 5 illustrates an example of a method of displaying a message or a messenger after the interruption of an incoming call according to various embodiments of the present disclosure. When UE 2 415 identifies, in operation 470 of FIG. 4, that UE 1 400 of the user who wants to make a voice call is in the messenger mode, UE 2 415 immediately displays, on the screen thereof, a list of a text message application 500 and messenger applications 505, 510, 515, and 520, through which communication is possible, in order to reduce the operating procedure of the user of UE 2. When the user of UE 2 selects one of the text message application and the messenger applications in the list, UE 2 415 switches to a dialogue window of the selected application and send messages to the user of UE 1 400. In order to further reduce the user's operating procedure, UE 2 415 identifies the messenger mode of UE 1 400 and then immediately displays, on the screen thereof, a text message window or a dialogue window of a messenger application that has been designated in advance by the user. The dialogue window of the messenger application basically includes dialogue boxes 525 for displaying dialogue contents sent by the users of UE 1 400 and UE 2 415, an input window 530 for receiving an input of a dialogue, and a send button 535 for instructing an input dialogue to be sent.

FIG. 6 illustrates an example of a procedure of receiving an application message in a messenger mode according to various embodiments of the present disclosure.

In FIG. 6, a specific communication service provider, for example, a messenger provider or an e-mail provider 615 attempts to provide application data to a user of UE 1 600.

In operation 620, the user of UE 1 600 switches to a messenger mode according to his or her specific intention. In operation 625, UE 1 600 transmits a messenger mode activation request message to a call session control server 605. The call session control server 605 functions to handle a part relating to call and session processing and serves as a gateway for an incoming call. The message is for informing the call session control server 605 that the UE switches to the messenger mode. The message includes a list of messenger applications that the user is using, and a list of uninterrupted telephone numbers. The message information is used for selectively providing a communication service to the UE. In operation 630, the call session control server 605 stores the telephone number list included in the message.

In operation 635, the call session control server 605 transmits a messenger mode application message to a messenger mode server. The message includes the messenger application list. At the same time, in operation 640, the call session control server 605 selectively provides new setting information to UE 1 600. The new setting information includes setting information to which a very long DRX period is applied to maximize power consumption.

In operation 645, the e-mail server 615 attempts to transmit application data to UE 1 600. The data is an e-mail reception notification message, a received mail list, and the like. In operation 650, the messenger mode server 610 having received the data identifies whether the data corresponds to application data included in the messenger application list. When the data corresponds to the data (message) of the messenger application, the messenger mode server 610 transmits the application data to UE 1 600 in operation 655. When the data does not correspond to the messenger application data, the messenger mode server 610 sends an acknowledgement message for informing that the receiver's UE is in the messenger mode, to the e-mail server in operation 660. In operation 665, the messenger mode server stores the application data. This is to immediately transmit data to UE 1 600 when the messenger mode of UE 1 600 is disabled later.

In operation 670, the user of UE 1 600 disables the messenger mode. In operation 675, UE 1 600 transmits a messenger mode deactivation message to the call session control server 605.

In FIG. 7, it is exemplified that a user of UE 2 715 attempts to send an SMS/MMS text message to a user of UE 1 700. Since the SMS/MMS text message is a communication service that is allowable in a messenger mode, a signaling process is relatively simple, compared to the procedure for the incoming call control. In operation 720, the user of UE 1 700 switches to a messenger mode according to his or her specific intention. In operation 725, UE 1 700 transmits a messenger mode activation request message to a call session control server 705. In operation 730, the call session control server 705 stores a telephone number list included in the message. In operation 735, the call session control server 705 transmits a messenger mode application message to a messenger mode server. In operation 740, the call session control server selectively provides new DRX setting information to UE 1 700. In operation 745, UE 2 715 attempts to send an SMS/MMS text message to UE 1 700. Since the SMS/MMS text message is a communication service that is allowable in the messenger mode, the call session control server is going to immediately forward the SMS/MMS text message to UE 1 700 without any special determination process in operation 750. In operation 755, the call session control server transmits the SMS/MMS text message to UE 1.

FIG. 8 illustrates an example of a control procedure for an incoming call according to various embodiments of the present disclosure.

In operation 1220, the server receives application data from a communication service provider. The application data includes an e-mail reception notification message, a received e-mail list, and the like.

In operation 1230, the server compares the application data with the messenger application list. If the application list includes an application corresponding to the application data, the server transmits a message to the UE, and if the application list does not include an application corresponding to the application data, the server transmits an acknowledgement message to the communication service provider.

FIG. 13 is a block diagram of a UE according to various embodiments of the present disclosure.

Referring to FIG. 13, the UE includes a Radio Frequency (RF) processing unit 1310, a baseband processing unit 1320, a storage unit 1330, a controller 1340, and a display unit 1350.

The RF processing unit 1310 performs a function for transmitting and receiving a signal through a wireless channel, such as band conversion and amplification of a signal. The RF processing unit 1310 subjects a baseband signal provided from the baseband processing unit 1320 to up-conversion to an RF band signal and then transmits the converted signal through an antenna, and subjects an RF band signal received through the antenna to down-conversion to a baseband signal. For example, the RF processing unit 1310 includes a transmission filter, a reception filter, an amplifier, a mixer, an oscillator, a Digital-to-Analog Converter (DAC), an Analog-to-Digital Converter (ADC), and the like. Although only one antenna is illustrated in FIG. 13, the transmitting end includes a plurality of antennas.

The baseband processing unit 1320 performs a conversion between a baseband signal and a bit string according to a physical layer standard of a system. For example, the baseband processing unit 1320, when transmitting data, generates complex symbols by encoding and modulating a transmission bit string. In addition, the baseband processing unit 1320, when receiving data, recovers a reception bit string through the demodulation and decoding of a baseband signal provided from the RF processing unit 1310. For example, in the case of following the OFDM scheme, the baseband processing unit 1320, when transmitting data, generates complex symbols by encoding and modulating a transmission bit string, maps the complex symbols with sub-carriers, and then configures Orthogonal Frequency Division Multiplexing (OFDM) symbols through an Inverse Fast Fourier Transform (IFFT) operation and Cyclic Prefix (CP) insertion. In addition, the baseband processing unit 1320, when receiving data, divides a baseband signal provided from the RF processing unit 1310 in units of OFDM symbols, recovers signals mapped with sub-carriers through an FFT operation, and then recovers a reception bit string through demodulation and decoding. The baseband processing unit 1320 and the RF processing unit 1310 transmit and receive signals as described above. Accordingly, the baseband processing unit 1320 and the RF processing unit 1310 is referred to as a transmitter, a receiver, a transmitter/receiver, or a communication unit.

The storage unit 1330 stores data such as a basic program, an application program, and setting information for the operation of a device for data transfer rate control. In particular, the storage unit 1330 stores information relating to a non-messenger mode applied telephone number list and a messenger application list. In addition, the storage unit 1330 provides data stored therein according to a request of the controller 1340.

The controller 1340 controls overall operations of a device for managing a messenger mode. For example, the controller 1340 accesses a base station by transmitting a signal through the baseband processing unit 1320 and the RF processing unit 1310. The controller controls the device for managing a messenger mode to perform the procedures illustrated in FIGS. 2 to 9. According to various embodiments of the present disclosure, the operation of the controller 1340 is as follows.

The controller 1340 controls the setting of a messenger mode. The controller receives ACB information from a base station and set the mode of a UE to the messenger mode when an access priority is determined to be low. In addition, the controller identifies the battery capacity of the UE and set the mode of the UE to the messenger mode when the battery residual quantity is less than a preset value. The messenger mode is characterized by receiving only exceptionally set calls and interrupting the remaining calls for voice calls, and receiving only application messages or SMS/MMS messages.

The display unit 1350 receives information from the controller and displays the same on the screen of hardware. For example, the display unit 1350 displays icons and application execution screens on the screen thereof on the basis of communication service information from the controller.

FIG. 14 illustrates a server according to various embodiments of the present disclosure.

Referring to FIG. 14, the server includes a communication unit 1410, a storage unit 1420, and a controller 1430.

The communication unit 1410 performs a function for transmitting and receiving a signal through a wireless channel, such as band conversion and amplification of a signal. The communication unit 1410 performs a conversion between a baseband signal and a bit string according to a physical layer standard of a system. Accordingly, the communication unit 1410 is referred to as a transmitter, a receiver, or a transmitter/receiver.

The storage unit 1420 stores data such as a basic program, an application program, and setting information for the operation of a device for controlling a call session control server. In particular, the storage unit 1420 stores information on a messenger mode activation request message including information that an incoming call is interrupted, a non-messenger mode applied telephone number list, a messenger application list, and the like. In addition, the storage unit 1420 provides data stored therein according to a request of the controller 1430.

The controller 1430 controls overall operations of a device for managing a messenger mode. For example, the controller 1430 transmits a signal through the communication unit 1410. The controller controls the device for controlling the call session control server to perform the procedures illustrated in FIGS. 8, 9, and 11.

The controller 1430 performs a control according to a messenger mode activation request message. The controller restricts an incoming call according to incoming call interruption information, performs paging to the UE for an incoming call included in the non-message mode applied telephone number list, and forwards a call processing message to a messenger mode server for an incoming call not included in the non-messenger mode applied telephone number list.

The messenger mode is also used when the UE accesses a mobile communication network using an embedded Universal Integrated Circuit Card (eUICC).

FIG. 15 illustrates an example of a wireless communication method between a UE and a communication service provider according to various embodiments of the present disclosure.

Referring to FIG. 15, FIG. 15 (a) illustrates a case in which a user connects to a wireless communication network through a Universal Integrated Circuit Card (UICC). In FIG. 15 (a), a UE 1510 communicates with a mobile communication service provider 1530 using a UICC 1520. The UICC 1520 provides a service only for a specific mobile communication service provider since only authentication information for the network access of a one specific mobile communication service provider is included in each UICC. Therefore, the user accesses the network of the specific mobile communication service provider 1530 according to the UICC 1520 by inserting the UICC 1520 into the UE 1510.

FIG. 15B illustrates a case in which a user connects to a wireless communication network through an embedded Universal Integrated Circuit Card (eUICC). In FIG. 15 (b), a UE 1550 communicates with a mobile communication service provider 1570 using an eUICC 1560. Unlike the UICC 1520 providing only a service for a predetermined specific mobile communication service provider, the eUICC 1560 allows the user to determine a specific mobile communication service provider among a plurality of mobile communication service providers to use a service that the corresponding communication service provider provides. When the user requests the specific mobile communication service provider 1570 to provide a service, using the UE including the eUICC 1560 embedded therein, the specific mobile communication service provider 1570 requests a profile providing server 1580 to download a profile, and the profile providing server 1580 encrypts the profile of the specific mobile communication service provider 1570 and then transfers the same to a profile managing server 1590. When the profile managing server 1590 transfers the encrypted profile to the eUICC using the Over The Air (OTA) technology, the UE 1550 downloads and installs the received encrypted profile to access the network of the specific mobile communication service provider 1570.

The eUICC 1560 has an eUICC Identifier (eUICCID), a secret key, and an OTA key recorded therein and includes a plurality of storage spaces. The eUICCID is unique identification information of the eUICC 1560 that is transferred to a network provider when the user subscribes to the network provider. The secret key is an encryption key for the eUICC 1560, which is used when a profile is encrypted and transferred to the eUICC 1560. The OTA key is a key for the management of the eUICC 1560, which is used for secondary encrypting of the eUICC profile.

Each of the storage spaces is used for storing a profile, and the profile store information included in the UICC. For example, the profile includes Universal Integrated Circuit Card Identifier (UICCID) information, Universal Subscriber Identity Module (USIM) information, banking information, and the like. A profile generated from a specific network provider is stored and activated in any one of the storage spaces so that the eUICC functions as an eUICC of the network provider.

Through the wireless communication network access using the eUICC, the user selects a specific mobile communication service provider among a plurality of mobile communication service providers to receive a wireless communication network service. In order to select the specific mobile communication service provider, the user accesses an intermediary server that sells a mobile communication network service.

FIG. 16 illustrates an example of providing a service for the selection of a service product that provides a wireless communication network service according to various embodiments of the present disclosure.

FIG. 16 illustrates an example 1610 of the screen display in cases where a user accesses an intermediary server that sells a mobile communication network service. The user accesses the intermediary server to identify service contents that a mobile communication service provider provides. The service contents include information on a mobile communication service provider 1620, a payment system 1630, provided service contents 1640, and the like. The information on the payment system 1630 and the provided service contents 1640 includes information on payment in advance or later, information on a monthly service fee, information on a lump sum payment, information on pre-tax or after-tax, information on the amount of calls to be available, information on the amount of data to be available, information on a method of deducting the amount of calls to be available, information on a method of deducting the amount of data to be available, and information on an additional service.

The information is displayed as text or an image. The location and the sequence in which the information is displayed are determined by a service provider of a server that plays an intermediary role in the trade of communication service products.

FIG. 17 illustrates an example of a communication service opening process of a UE using an eUICC according to various embodiments of the present disclosure.

In operation 1710, the UE 1701 accesses the intermediary server 1703 that plays an intermediary role in the trade of profiles between the mobile communication service provider 1705 and the UE 1701 of a user. Although only one intermediary server 1703 is illustrated in the drawing, a plurality of intermediary servers is provided, in which case the UE 1701 accesses a specific intermediary server among the plurality of intermediary servers. In cases where the plurality of intermediary servers are provided, the UE 1701 accesses an intermediary server set as a default or accesses other intermediary servers according to sites. The access to the intermediary server 1703 is made manually by a user selection or automatically by the UE. The user accesses the intermediary server 1703 by executing a specific application of the UE 1701 or manually accesses the intermediary server 1703 through a selection on a specific screen of a specific application. In addition, the UE 1701 automatically accesses the intermediary server 1703 in cases where a profile through which a communication service is available at present does not exist or in cases where a communication service is available only through roaming and there is no profile of a local network user. The UE 1701 accesses the intermediary server 1703 by providing the user's Identification (ID) and password, or by providing the user's telephone number, and transmits eUICC identifier information for distinguishing the eUICC included in the UE to the intermediary server 1703.

In operation 1720, the intermediary server 1703 provides product information to the UE 1701. When the UE 1701 accesses the intermediary server 1703, the intermediary server 1703 transmits information for subscribing to or purchasing a communication product to the UE 1701. The information is displayed as text or an image. The information include information on the mobile communication service provider 1705, a payment system, provided service contents, and the like, and the location and the sequence in which the information is displayed is determined by a service provider of the intermediary server 1703. The UE 1701 displays the information received from the intermediary server 1703. The UE 1701 displays the information as illustrated in FIG. 2 or displays the symbol or the communication company name of the mobile communication service provider 1705. When the user selects the symbol or the name of the corresponding mobile communication service provider, the UE 1701 also displays available payment systems. In addition, the UE 1701 displays the fact that the network access information of the mobile communication service provider 1705 is downloaded through a network. The UE 1701 displays a screen through which the user determines a selection of a communication product of a specific mobile communication service provider. For example, the UE 1701 displays a screen for selecting a communication product payment method and displays a screen for inputting credit card or bank account information as the payment method. In certain embodiments, the UE 1701 may also omit the payment method selecting process without providing a separate screen.

In operation 1730, the UE 1701 transmits product purchase information to the intermediary server 1703. The product purchase information includes a product identifier, an eUICC identifier, and payment information. The product identifier includes information for distinguishing the selection of a specific mobile communication company and a specific payment system. The payment information includes credit card information or bank account information or includes information for notifying of the use of credit card or bank account information stored in the intermediary server 1703.

In operation 1740, the intermediary server 1703, after receiving the product purchase request information from the UE 1701, transmits product purchase processing request information to the mobile communication service provider 1705 according to the product identifier. For example, when information on a specific mobile communication service provider is included in the product identifier, the intermediary server 1703 transmits the product purchase processing request information to the corresponding specific mobile communication service provider 1705. In addition, the product identifier includes information on a payment system product, profile distinction information, and arbitrary information supported by the mobile communication service provider 1705. When the product identifier includes the profile distinction information, the profile identifier is an Integrated Circuit Card Identifier (ICCID) value. When the intermediary server 1703 transmits the eUICC identifier information, received from the UE 1701, to the mobile communication service provider 1705, the mobile communication service provider 1705 identifies an eUICC where a communication profile is to be installed.

In operation 1745, the mobile communication service provider 1705 performs approval for the product purchase processing request information received from the intermediary server 1703. After receiving the product purchase processing request from the intermediary server 1703, the mobile communication service provider 1705 updates information for providing a communication service to the UE 1701. For example, the mobile communication service provider 1705 updates an activation field corresponding to Integrated Mobile Subscription Identifier (IMSI) information mapped with the profile identifier to an authentication server. In addition, the mobile communication service provider 1705 performs mapping onto the profile identifier using the product identifier received from the intermediary server 1703. When a profile identifier is included in the product identifier, the included profile identifier is also used.

In operation 1750, the mobile communication service provider 1705 transmits a profile download request message to the profile providing server 1707. The profile download request message includes the profile identifier and the eUICC identifier received from the intermediary server 1703.

In operation 1760, the profile providing server 1707 requests the profile managing server 1709 to download a profile. Although the term ‘profile providing server’ is used in certain embodiments of the present disclosure, the profile providing server 1707 is Subscription Management Data Preparation (SM-DP), a profile provider, a profile provisioner, a profile provisioning credentials holder, or the like. The profile providing server 1707 preserves profile information including subscriber information installed in the eUICC and creates a profile in the fond that can be installed in the eUICC. When receiving the profile download request from the mobile communication service provider 1705, the profile providing server 1707 creates a profile to allow the eUICC corresponding to the eUICC identifier to download the profile, using the received eUICC identifier and the profile identifier. The profile providing server 1707 transmits a download request message to the profile managing server 1709 to allow the UE 1701 to download the created profile. The profile is transmitted through the download request message or another form of message. The transmission is performed by transmitting a message once or by exchanging messages several times.

In operation 1770, the profile managing server 1709 transmits the profile to the UE 1701. Although the term ‘profile managing server’ is used in the embodiment of the present disclosure, the profile managing server 1709 is Subscription Manager Secure Routing (SM-SR), a profile manager, a profile management credentials holder, or the like. The profile managing server 1709 remotely transmits the profile to the UE corresponding to the eUICC, using the eUICC identifier included in the profile download request message received from the profile providing server 1707. The transmission is performed through message transmission/reception using a Short Message Service (SMS), message transmission/reception using IP communication of a mobile communication network, or message transmission/reception using IP communication through short-range communication technology, such as Wireless Fidelity (WiFi), Bluetooth, Near Field Communication (NFC), or the like, or Universal Serial Bus (USB) connection with a UE having a communication function. In the process of transmitting the profile, the profile managing server 1709 transmits the profile or the profile data received from the profile providing server 1707 to the UE 1701, and transmits a processing result received from the UE 1701 to the profile providing server 1707. If the profile managing server 1709 fails to receive the processing result from the UE 1701, the profile managing server 1709 transmits the corresponding profile or profile data again. The profile managing server 1709 stores all or some data of the profile download request message received from the profile providing server 1707 without transmitting the same, and when receiving a download request from the UE 1701, transmits the profile or profile data to the UE 1701.

The UE 1701 downloads the profile from the profile managing server 1709, activate the downloaded profile and accesses the corresponding mobile communication company to use a communication service. The activation of the profile is selected by the user or is automatically selected using information included in a message received from the profile managing server 1709. When the profile is completely downloaded, the UE 1701 accesses the profile managing server 1709 or the intermediary server 1703 to transmit information as to whether the download is completed. The information as to whether the download is completed includes the eUICC identifier and the profile ID.

The profile managing server 2109 stores all or some data of the profile download request message received from the profile providing server 2107 without transmitting the same, and when receiving a download request from the UE 2101, transmits the profile or profile data to the UE 2101.

The UE 2101 downloads the profile from the profile managing server 2109, activates the downloaded profile, and accesses the corresponding mobile communication company to use a communication service. The activation of the profile is selected by the user or is automatically selected using information included in a message received from the profile managing server 2109. When the profile is completely downloaded, the UE 2101 accesses the profile managing server 2109 or the intermediary server 2103 to transmit information as to whether the download is completed. The information as to whether the download is completed includes the eUICC identifier and the profile ID.

FIG. 22 illustrates an example of a communication service opening process of a UE using an eUICC depending on location information according to various embodiments of the present disclosure.

Referring to FIG. 22, the communication service opening process of a UE using an eUICC is performed through communication among a UE 2201, an intermediary server 2203, a mobile communication service provider 2205, a profile providing server 2207, and a profile managing server 2209.

In operation 2210, the UE 2201 accesses the intermediary server 2203 that plays an intermediary role in the trade of profiles between the mobile communication service provider 2205 and the user UE 2201. Although only one intermediary server 2203 is illustrated in the drawing, a plurality of intermediary servers is provided, in which case the UE 2201 accesses a specific intermediary server among the plurality of intermediary servers. In cases where the plurality of intermediary servers are provided, the UE 2201 accesses an intermediary server set as a default or accesses other intermediary servers according to sites. The access to the intermediary server 2203 is made manually by a user selection or automatically by the UE. The user accesses the intermediary server 2203 by executing a specific application of the UE 2201 or manually accesses the intermediary server 2203 through a selection on a specific screen of a specific application. In addition, the UE 2201 automatically accesses the intermediary server 2203 in cases where a profile through which a communication service is available at present does not exist, or in cases where a communication service is available only through roaming and there is no profile of a local network user. The UE 2201 accesses the intermediary server 2203 by providing the user's Identification (ID) and password, or by providing the user's telephone number, and transmits a UE identifier for distinguishing the eUICC included in the UE to the intermediary server 2203. The UE identifier includes the capability information of the UE 2201. According to the various embodiments of the present disclosure, the UE identifier is a value by which the intermediary server 2203 distinguishes the UE, and an International Mobile Equipment Identity (IMEI) value is included as an example of the UE identifier. The location information includes the location of the corresponding UE, for example, national information. The location information includes a Public Land Mobile Network (PLMN) ID scanned by the UE, the IP of the UE used by the UE, a Network Address Translation (NAT) IP of a wireless router used by the UE, a Global Positioning System (GPS) information measured by the UE, the name of a country selected by the user, ID information used by the user, the entirety or a portion of a corresponding telephone number in cases where the UE accesses with an eUICC profile that is open in advance, and information on a communication company to which the corresponding telephone number is registered in cases where the UE accesses with the eUICC profile that is open in advance. If the location information includes a plurality pieces of information, for example, if the name of a country selected by the user is the USA and the PLMN ID value scanned by the UE is 450 (Korea), the intermediary server 2203 provides an American communication company profile and transmits the location of the UE to the American communication company so that the location of the UE is utilized in services of the corresponding communication company. For example, a user who uses a communication service in Korea opens an American communication service in advance in Korea before going to the USA.

In operation 2220, the intermediary server 2203 provides product information to the UE 2201. The intermediary server 2203 displays only communication companies that can provide a service to the UE and product information thereof, using the UE identifier received from the UE 2201. The communication companies that can provide a service and the product information thereof vary depending on whether the UE 2201 supports a service, such as Long Term Evolution (LTE) or 3Generation (3G), in a specific frequency range of a communication service. In addition, the intermediary server 2203 provides only the communication companies that can provide a service and the product information thereof to the UE using the location information. For example, when the location information received from the UE is a PLMN ID, and the Mobile Operator Code (MOC) value of the PLMN ID is 450, the intermediary server 2203 provides a communication company profile that can be used in Korea. When the UE 2201 accesses the intermediary server 2203, the intermediary server 2203 transmits information for subscribing to or purchasing a communication product to the UE 2101. The information is displayed as text or an image. The information includes information on the mobile communication service provider 2205, a payment system, provided service contents, and the like, and the location and the sequence in which the information is displayed is determined by a service provider of the intermediary server 2203. The UE 2201 displays the information received from the intermediary server 2203. The UE 2201 displays the information as illustrated in FIG. 2 or displays the symbol or the communication company name of the mobile communication service provider 2205. When the user selects the symbol or the name of the corresponding mobile communication service provider, the UE 2101 also display available payment systems. In addition, the UE 2201 displays the fact that the network access information of the mobile communication service provider 2205 is downloaded through a network. The UE 2201 displays a screen through which the user determines a selection of a communication product of a specific mobile communication service provider. For example, the UE 2201 displays a screen for selecting a communication product payment method and displays a screen for inputting credit card or bank account information as the payment method. In certain embodiments, the UE 2201 may also omit the payment method selecting process without providing a separate screen.

In operation 2230, the UE 2201 transmits product purchase information to the intermediary server 2203. The product purchase information includes a product identifier, an eUICC identifier, the UE identifier, the location information, and payment information. The product identifier includes information for distinguishing the selection of a specific mobile communication company and a specific payment system. The payment information includes credit card information or bank account information or includes information for notifying of the use of credit card or bank account information stored in the intermediary server 2203.

In operation 2240, the intermediary server 2203, after receiving the product purchase request information from the UE 2201, transmits product purchase processing request information to the mobile communication service provider 2205 according to the product identifier. For example, if information on a specific mobile communication service provider is included in the product identifier, the intermediary server 2203 transmits the product purchase processing request information to the corresponding specific mobile communication service provider 2205. In addition, the product identifier includes information on a payment system product, profile distinction information and arbitrary information supported by the mobile communication service provider 2205. If the product identifier includes the profile distinction information, the profile identifier is an Integrated Circuit Card Identifier (ICCID) value. When the intermediary server 2203 transmits the eUICC identifier information, received from the UE 2201, to the mobile communication service provider 2205, the mobile communication service provider 2205 identifies an eUICC where a communication profile is to be installed.

In operation 2250, the mobile communication service provider 2205 performs approval for the product purchase processing request information received from the intermediary server 2203.

FIG. 25 illustrates an example of a communication service opening process of a UE using an eUICC through storing a profile in advance according to various embodiments of the present disclosure.

Referring to FIG. 25, the communication service opening process of a UE using an eUICC through storing a profile in advance is performed through communication among a UE 2501, an intermediary server 2503, a mobile communication service provider 2505, a profile providing server 2507, and a profile managing server 2509.

In operation 2510, the UE 2501 accesses the intermediary server 2503 that plays an intermediary role in the trade of profiles between the mobile communication service provider 2505 and the user UE 2501. Although only one intermediary server 2503 is illustrated in the drawing, a plurality of intermediary servers is provided, in which case the UE 2501 accesses a specific intermediary server among the plurality of intermediary servers. In cases where the plurality of intermediary servers are provided, the UE 2501 accesses an intermediary server set as a default or accesses other intermediary servers according to sites. The access to the intermediary server 2503 is made manually by a user selection or automatically by the UE. The user accesses the intermediary server 2503 by executing a specific application of the UE 2501 or manually accesses the intermediary server 2503 through a selection on a specific screen of a specific application. In addition, the UE 2501 automatically accesses the intermediary server 2503 in cases where a profile through which a communication service is available at present does not exist, or in cases where a communication service is available only through roaming and there is no profile of a local network user. The UE 2501 accesses the intermediary server 2503 by providing the user's Identification (ID) and password, or by providing the user's telephone number, and transmits eUICC identifier information for distinguishing the eUICC included in the UE to the intermediary server 2503.

In operation 2520, the intermediary server 2503 provides product information to the UE 2501. When the UE 2501 accesses the intermediary server 2501, the intermediary server 2503 transmits information for subscribing to or purchasing a communication product to the UE 2501. The information is displayed as text or an image. The information includes information on the mobile communication service provider 2505, a payment system, provided service contents, and the like, and the location and the sequence in which the information is displayed is determined by a service provider of the intermediary server 2503. The UE 2501 display the information received from the intermediary server 2503. The UE 2501 displays the information as illustrated in FIG. 2 or displays the symbol or the communication company name of the mobile communication service provider 2505. When the user selects the symbol or the name of the corresponding mobile communication service provider, the UE 2501 also displays available payment systems. In addition, the UE 2501 displays the fact that the network access information of the mobile communication service provider 2505 is downloaded through a network. The UE 2501 displays a screen through which the user determines a selection of a communication product of a specific mobile communication service provider. For example, the UE 2501 displays a screen for selecting a communication product payment method and displays a screen for inputting credit card or bank account information as the payment method. In certain embodiments, the UE 2501 also omits the payment method selecting process without providing a separate screen.

In operation 2530, the UE 2501 transmits product purchase information to the intermediary server 2503. The product purchase information includes a product identifier, an eUICC identifier, and payment information. The product identifier includes information for distinguishing the selection of a specific mobile communication company and a specific payment system. The payment information includes credit card information or bank account information or includes information for notifying of the use of credit card or bank account information stored in the intermediary server 2503.

In operation 2540, the intermediary server 2503, after receiving the product purchase request information from the UE 2501, transmits product purchase processing request information to the mobile communication service provider 2505 according to the product identifier. For example, if information on a specific mobile communication service provider is included in the product identifier, the intermediary server 2503 transmits the product purchase processing request information to the corresponding specific mobile communication service provider 2505. In addition, the product identifier includes information on a payment system product, profile distinction information, and arbitrary information supported by the mobile communication service provider 2505. If the product identifier includes the profile distinction information, the profile identifier is an Integrated Circuit Card Identifier (ICCID) value. When the intermediary server 2503 transmits the eUICC identifier information, received from the UE 2501, to the mobile communication service provider 2505, the mobile communication service provider 2505 identifies an eUICC where a communication profile is to be installed.

In operation 2545, the mobile communication service provider 2505 performs approval for the product purchase processing request information received from the intermediary server 2503. After receiving the product purchase processing request from the intermediary server 2503, the mobile communication service provider 2505 updates information for providing a communication service to the UE 2501. For example, the mobile communication service provider 2505 updates an activation field corresponding to Integrated Mobile Subscription Identifier (IMSI) information mapped with the profile identifier to an authentication server. In addition, the mobile communication service provider 2505 performs mapping onto the profile identifier using the product identifier received from the intermediary server 2503. If a profile identifier is included in the product identifier, the included profile identifier is also used.

In operation 2550, the profile providing server 2507 provides a profile to the profile managing server 2509. The profile providing server 2507 stores a plurality of profiles in advance in the profile managing server 2509. The storing of the profiles is performed by manually controlling the profile providing server 2507 or automatically under a specific condition. The profile providing server 2507 provides an encrypted profile. In cases where a profile is encrypted such that it is decoded only in a predetermined eUICC and transferred to the profile providing server, the corresponding profile is installed only in the corresponding eUICC. Furthermore, in cases where the corresponding encryption is performed with an arbitrary encryption key without being specified such that the encrypted profile is decoded only in a specific eUICC, the encrypted profile is specified such that it is decoded only in the specific eUICC of the profile managing server 2509. The process of decoding the encrypted profile only in the specific eUICC includes a process of decoding and re-encrypting the whole profile in the profile managing server 2509.

In operation 2560, the intermediary server 2503 requests the profile managing server 2509 to download a profile. The profile providing server 2507 preserves profile information including subscriber information installed in the eUICC and creates a profile in the form that can be installed in the eUICC. The profile managing server 2509 stores a plurality of profiles in advance, and when receiving the profile download request from the intermediary server 2503, the profile managing server 2509 immediately transfers a profile to the UE if the profile corresponding to the profile identifier included in the corresponding profile download request message has been stored in advance therein.

In operation 2570, the profile managing server 2509 transmits the profile to the UE 2501. The transmission is performed through message transmission or reception using a Short Message Service (SMS), message transmission or reception using IP communication of a mobile communication network, or message transmission or reception using IP communication through short-range communication technology, such as Wireless Fidelity (WiFi), BLUETOOTH, Near Field Communication (NFC), or the like, or Universal Serial Bus (USB) connection with a UE having a communication function. In the process of transmitting the profile, the profile managing server 2509 transmits the profile or the profile data received from the profile providing server 2507 to the UE 2501, and transmits a processing result received from the UE 2501 to the profile providing server 2507. If the profile managing server 2509 fails to receive the processing result from the UE 2501, the profile managing server 2509 transmits the corresponding profile or profile data again. The profile managing server 2509 stores all or some data of the profile download request message received from the profile providing server 2507 without transmitting the same, and when receiving a download request from the UE 2501, transmits the profile or profile data to the UE 2501.

The UE 2501 downloads the profile from the profile managing server 2509, activate the downloaded profile, and access the corresponding mobile communication company to use a communication service. The activation of the profile is selected by the user or is automatically selected using information included in a message received from the profile managing server 2509. When the profile is completely downloaded, the UE 2501 accesses the profile managing server 2509 or the intermediary server 2503 to transmit information as to whether the download is completed. The information as to whether the download is completed includes the eUICC identifier and the profile ID.

Referring to FIG. 37, the UE includes a Radio Frequency (RF) processing unit 3710, a baseband processing unit 3720, a storage unit 3730, a controller 3740, and a display unit 3750.

The RF processing unit 3710 performs a function for transmitting and receiving a signal through a wireless channel, such as band conversion and amplification of a signal. That is, the RF processing unit 3710 subjects a baseband signal provided from the baseband processing unit 3720 to up-conversion to an RF band signal and then transmits the converted signal through an antenna, and subjects an RF band signal received through the antenna to down-conversion to a baseband signal. For example, the RF processing unit 3710 includes a transmission filter, a reception filter, an amplifier, a mixer, an oscillator, a Digital-to-Analog Converter (DAC), an Analog-to-Digital Converter (ADC), and the like. Although only one antenna is illustrated in FIG. 37, the UE includes a plurality of antennas. In addition, the RF processing unit 3710 includes a plurality of RF chains. In order to transmit and receive information relating to an eUICC, the RF processing unit 3710 adjusts the phase and magnitude of signals transmitted and received through a plurality of antenna or antenna elements.

The baseband processing unit 3720 performs a conversion between a baseband signal and a bit string according to a physical layer standard of a system. For example, the baseband processing unit 3720, when transmitting data, generates complex symbols by encoding and modulating a transmission bit string.
